The mined ore is transported by conveyor system to large above-ground or underground silos where it is stored until it is used in production. Reliable level measurement is required to determine the contents of silos.

Challenge:

The temperature of the blast furnace silo is relatively high, and its working temperature range is generally between 200 and 300°C; the dried raw materials, such as carbon, lime, ore, etc., will emit a large amount of dust suspended in the air during the feeding and production process , because the material ratio will change, and the mixing will be uneven, and it may also be affected by a small amount of steam, etc. These factors will interfere with the dielectric constant; the height of the blast furnace silo is much higher than that of ordinary containers, and the blocks inside it The solid material will have a large downward gravity impact on the measuring instrument during the feeding process, and each time it will cause different degrees of wear to the measuring instrument.
